Paper Abstract

Terahertz technology exploits the so-called frequency gap between the infrared and microwaves, typically referred to as the frequency band from 100 GHz to 30 Terahertz. The use of techniques based on the Terahertz radiation has long been studied in fields such as astronomy and solid state physics. Being a non harmful radiation for human beings, the Terahertz radiation is very interesting for applications since it can be used without worrying for the safety of users and operators. Recent innovations in Terahertz technologies are bringing a wide variety of applications, from non-destructive evaluation, to homeland security, from quality control of food and agricultural products to the biomedical sector.

We report about an implementation of a sub-Terahertz investigation setup based on commercial solutions. The system is currently being used for non-invasive detection of metals inside parcels and boxes in security applications and in vivo studies of water leaf contents in smart agriculture.
